Answer: 107.97
Explanation:
Nominal GDP for 1975 = 1975 quantity × 1975 prices
= (21 × 0.50) + ( 11 × 10.5 ) + ( 1 × 130 )
= 10.5 + 115.5 + 130
= 256.0
Real GDP for 1975 = 1975 quantity × 1970 prices
= (21 × 0.10) + ( 11 × 15 ) + ( 1 × 70 )
= 237.1
[tex]GDP\ delator=\frac{Nominal\ GDP}{Real\ GDP}\times100[/tex]
[tex]GDP\ delator=\frac{256.0}{237.1}\times100[/tex]
= 1.079 × 100
= 107.97
